Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 125,030,605, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 125,030,605 | |
| -1 | -125,030,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,030,605.
Example:
1 x 125,030,605 = 125,030,605
and
-1 x -125,030,605 = 125,030,605
Notice both answers equal 125,030,605
With that explanation out of the way, let's continue. Next, we take the number 125,030,605 and divide it by 2:
125,030,605 ÷ 2 = 62,515,302.5
If the quotient is a whole number, then 2 and 62,515,302.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 125,030,605 | |
| -1 | -125,030,605 |
Now, we try dividing 125,030,605 by 3:
125,030,605 ÷ 3 = 41,676,868.3333
If the quotient is a whole number, then 3 and 41,676,868.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 125,030,605 | |
| -1 | -125,030,605 |
Let's try dividing by 4:
125,030,605 ÷ 4 = 31,257,651.25
If the quotient is a whole number, then 4 and 31,257,651.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 125,030,605 | |
| -1 | 125,030,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 179 | 245 | 895 | 1,253 | 2,851 | 6,265 | 8,771 | 14,255 | 19,957 | 43,855 | 99,785 | 139,699 | 510,329 | 698,495 | 2,551,645 | 3,572,303 | 17,861,515 | 25,006,121 | 125,030,605 |
| -1 | -5 | -7 | -35 | -49 | -179 | -245 | -895 | -1,253 | -2,851 | -6,265 | -8,771 | -14,255 | -19,957 | -43,855 | -99,785 | -139,699 | -510,329 | -698,495 | -2,551,645 | -3,572,303 | -17,861,515 | -25,006,121 | -125,030,605 |
